Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of desk calendar binding, in particular to a desk calendar automatic ring threading device and a binding production line thereof. BACKGROUND

[0002] Desk calendars, as a common daily office supplies and promotional gifts, have a large market demand, especially in export business, often face the production task of large quantities and short delivery period. At present, the binding process of desk calendars usually includes two core steps of punching and ring binding: first, regular arranged holes are punched in the same position of the hard cover and all the inner pages; then a ring-shaped binding part (usually a coil, a ring buckle, etc. of metal or plastic material) is threaded through all the holes, and the two ends are closed and locked by using a tool, so that the cover and the inner pages are firmly assembled into one.

[0003] In the prior art, the above-mentioned ring binding step mainly relies on manual operation. The operator needs to manually thread the ring-shaped binding part through the neatly stacked desk calendar holes, and then use a handheld tool (such as a special pliers, a pressing pliers, etc.) to apply pressure to the two ends of the binding part to make them clasp each other, thereby completing the binding. But this manual operation mode has the following obvious defects:

[0004] 1. Low production efficiency: the manual threading and clamping actions are repetitive and tedious, and the binding of a single desk calendar takes a long time, which cannot meet the large-scale and intensive production demand, and becomes the bottleneck process of the whole desk calendar production process, especially difficult to adapt to the common explosive orders in export business.

[0005] 2. High labor cost and poor stability: intensive manual operation requires a large amount of labor, resulting in a continuous rise in production cost. At the same time, the rhythm and efficiency of manual operation are easily affected by factors such as worker fatigue and proficiency, and the production rhythm is unstable, making it difficult to achieve balanced production.

[0006] 3. Safety hazards and occupational health problems: during the repeated pressing operation with pliers tools, the operator's hands, especially the palms and fingers, need to continuously bear a large counterforce, which can easily lead to muscle strain, joint pain and even tendinitis and other occupational diseases in the long run. In addition, sharp metal ring edges or improper use of tools may also cause cuts and other work accidents.

[0007] 4. Inconsistent binding quality: manual operation cannot guarantee that the force and angle of clamping are exactly the same every time, which can easily lead to loose closure of some ring-shaped binding parts, or damage to the binding parts or desk calendar pages due to excessive force, affecting the appearance and service life of the product, and ultimately leading to fluctuations in the yield of finished products.

[0008] In summary, there is an urgent need in the market for an automatic device that can realize the automatic ring threading of desk calendars and even the entire binding process, so as to get rid of the dependence on manual operation, thereby improving the production efficiency and the consistency of product quality, and guaranteeing the personal safety and health of the operating personnel.

Therefore, the features defined with “first”, “second” can explicitly or implicitly include at least one of the features.

[0034] In the description of the embodiments, unless otherwise explicitly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] Example 1:

[0036] like Figure 1 As shown, the automatic calendar threading device in this embodiment includes a feeding channel 10, a fixed plate 20, a movable plate 30, a closing mechanism 40, a threading mechanism 50, a driving cylinder 60, and an auxiliary feeding mechanism 70. The feeding channel 10 is located on the rear side of the fixed plate 20, and the outlet of the feeding channel 10 is located on the upper side of the fixed plate 20. The inlet of the feeding channel 10 extends to the far end of the fixed plate 20, and the movable plate 30 is located on the front side of the fixed plate 20.

[0037] The closing mechanism 40 is set on the movable plate 30 and located on the left and right sides of the discharge port of the feeding channel 10 respectively. The ring-passing mechanism 50 is set on the movable plate 30. The driving cylinder 60 is set on the fixed plate 20 along the longitudinal direction and is connected to the movable plate 30 in a transmission connection. The two sides of the movable plate 30 are slidably connected to the fixed plate 20 through the slide rail assembly.

[0038] like Figure 2 As shown, the feeding channel 10 includes a guide rod 11, a support rod 12, and a limiting cover 13. The guide rod 11 is a horizontally arranged figure-eight shaped rod, the support rod 12 is arranged parallel to the bottom of the guide rod 11, and the limiting cover 13 is arranged on the outside of the guide rod 11.

[0039] Before closing, the calendar ring 80 is shaped like the letter "3" and is placed horizontally between the guide rod 11 and the support rod 12, with both sides in contact with the inner wall of the limiting cover 13. The calendar ring 80 is partially wrapped around the lower side of the guide rod 11. In actual use, the device is set at an angle, that is, the feed port side of the feeding channel 10 is higher than the discharge port side, so that the calendar ring 80 can slide along the guide rod 11 and the support rod 12 to the closing mechanism 40.

[0040] Combination Figure 1 As shown, a linear vibrating feeder 14 is also provided on the upper side of the limit cover 13 near the feed inlet of the feeding channel 10. Under the vibration of the linear vibrating feeder 14, the calendar ring 80 is facilitated to slide into the closing mechanism 40 along the feeding channel 10. The linear vibrating feeder 14 adopts existing technology, such as the YQ-100T series linear vibrating feeder.

[0041] like Figure 3As shown, the closing mechanism 40 includes a closing cylinder 41 arranged laterally on the upper side of the movable plate 30 and a positioning block 42 arranged at the end of the piston rod of the closing cylinder 41, and the positioning block 42 is provided with an arc-shaped positioning groove 43 on the side facing the discharge port of the feeding channel 10, and the profile of the arc-shaped positioning groove 43 matches the shape of the calendar ring 80.

[0042] When the calendar ring 80 enters the closing mechanism 40 along the feeding channel 10, the two semicircular rings of the calendar ring 80 are just located in the arc-shaped positioning grooves 43 on both sides.

[0043] As shown, Figure 4 The threading mechanism 50 includes a positioning plate 51 arranged on the movable plate 30, a guide plate 52 arranged on the front side of the positioning plate 51 and movably connected with the guide blocks 21 arranged on the fixed plate 20 at both ends, and two positioning columns 53 symmetrically arranged on the guide plate 52 and having a spacing matching the lateral dimension of the calendar ring 80 after being unfolded; one end of the positioning column 53 is fixedly connected with the guide plate 52, and the other end movably penetrates the positioning plate 51.

[0044] The guide block 21 is L-shaped, with the short arm of the lower end fixed on the fixed plate 20 and the long arm of the upper end extending to the front side of the movable plate 30 without contacting the movable plate 30. The inner side of the guide block 21 is provided with a track groove 22, and the upper side of the track groove 22 is provided with a wedge surface 23 inclined to the front side, and the end of the guide plate 52 is rollingly connected with the track groove 22 through a cam roller 54.

[0045] In the initial state, the piston rod of the driving cylinder 60 is in the retracted state, the cam roller 54 is located in the track groove 22, and the positioning column 53 is located in the arc-shaped positioning groove 43 and abuts against the inner wall of the semicircular rings on both sides of the calendar ring 80, thereby ensuring that the calendar ring 80 is in the unfolded state and preventing it from being closed.

[0046] When the driving cylinder 60 drives the movable plate 30 to move upward, the guide plate 52 moves upward along the track groove 22; when the cam roller 54 rolls upward along the wedge surface 23, it drives the guide plate 52 to move to the side away from the positioning plate 51, and at the same time, the positioning column 53 also retreats with the guide plate 52, so that the positioning column 53 is separated from the inner wall of the calendar ring 80 to avoid affecting the subsequent threading action.

[0047] The upper side of the movable plate 30 is provided with a bracket 31, the upper side of the bracket 31, the positioning plate 51 and the guide plate 52 are provided with a groove along the same straight line direction, which is used for supporting the desk calendar. In the process of upward movement of the movable plate 30, the bracket 31, the positioning plate 51, the guide plate 52 and the closing mechanism 40 move upward as a whole, lift the desk calendar, and drive the positioning block 42 to move through the closing cylinder 41, so that the arc-shaped positioning grooves 43 on both sides close the desk calendar ring 80, and the desk calendar ring 80 is worn in the hole previously punched on the desk calendar, so as to complete the ring wearing action of the desk calendar.

[0048] Specifically, the positioning plate 51 is provided with a proximity switch, when the desk calendar ring 80 enters the arc-shaped positioning groove 43, the proximity switch is powered and sends a signal to the driving cylinder 60, the driving cylinder 60 drives the movable plate 30 to move upward, and then the closing cylinder 41 drives the positioning block 42 to move, so that the arc-shaped positioning grooves 43 on both sides close the desk calendar ring 80.

[0049] As shown in Figure 5 The auxiliary feeding mechanism 70 is provided on the rear side of the fixed plate 20, the auxiliary feeding mechanism 70 includes a longitudinal moving cylinder 71, a transverse moving cylinder 72, a bracket 73 and a friction feeding block 74, the longitudinal moving cylinder 71 is arranged on the fixed plate 20 in the longitudinal direction, the bracket 73 is arranged on the piston rod end of the longitudinal moving cylinder 71, the transverse moving cylinder 72 is arranged on the bracket 73 in the transverse direction, and the friction feeding block 74 is arranged on the piston rod end of the transverse moving cylinder 72 and located on the lower side of the feeding channel 10.

[0050] The friction feeding block 74 can be made of soft material such as rubber or silica gel,

[0051] When the desk calendar ring 80 slides to the end of the feeding channel 10, the longitudinal moving cylinder 71 drives the bracket 73 to move upward, so that the friction feeding block 74 contacts the bottom of the desk calendar ring 80, then the transverse moving cylinder 72 drives the friction feeding block 74 to move to one side of the closing mechanism 40, and the desk calendar ring 80 is fed to the closing mechanism 40 through the friction between the friction feeding block 74 and the desk calendar ring 80. After feeding is completed, the longitudinal moving cylinder 71 and the transverse moving cylinder 72 are reset respectively. Each action realizes the feeding of a single desk calendar ring 80, and the continuous feeding of the desk calendar ring 80 is realized through such reciprocating cycle.

[0052] Embodiment two:

[0053] As shown in Figure 6As shown, the binding production line in the embodiment includes the automatic ring feeding device for desk calendar described above, and further includes a desk calendar frame feeding station 90, an inner page feeding station 100, a straightening mechanism 110, a punching mechanism 120, a stacking and clamping mechanism 130, and a book collecting mechanism 140 arranged in sequence. The desk calendar frame feeding station 90, the inner page feeding station 100, the straightening mechanism 110, and the stacking and clamping mechanism 130 are arranged in sequence along the same linear direction. The punching mechanism 120 is arranged opposite to the straightening mechanism 110. The chain book pushing mechanism 150 is arranged at the rear side of the desk calendar frame feeding station 90, the inner page feeding station 100, the straightening mechanism 110, and the punching mechanism 120. The book collecting mechanism 140 is arranged in a direction perpendicular to the stacking and clamping mechanism 130. The automatic ring feeding device for desk calendar in the first embodiment is arranged at the front side of the stacking and clamping mechanism 130.

[0054] The straightening mechanism 110, the punching mechanism 120, the stacking and clamping mechanism 130, and the chain book pushing mechanism 150 can all use the existing technologies in the field. For example, the straightening mechanism 110 can use the paper straightening mechanism for desk calendar and book punching machine disclosed in the patent CN219522291U previously applied by the applicant. The punching mechanism 120 can use the double-mold book punching device disclosed in the patent CN222553786U. The stacking and clamping mechanism 130 can use the book layering and stacking and pushing device disclosed in the patent CN219341189U. The chain book pushing mechanism 150 can use the double-chain book pushing device disclosed in the patent CN221643490U. The structure and working principle of each mechanism can refer to the related patent technologies.

[0055] The desk calendar frame feeding station 90 can be used in cooperation with the desk calendar frame feeding device, such as the automatic desk calendar frame arrangement device disclosed in the patent CN214564047U, so as to improve the feeding efficiency of the desk calendar frame.

[0056] The book collecting mechanism 140 uses the commonly used belt conveyor in the field. An arc-shaped guide plate 160 is arranged between the belt conveyor and the stacking and clamping mechanism 130, which is used to guide the ringed desk calendar to the book collecting mechanism 140 and then conveyed out by the book collecting mechanism 140.

[0057] The working process of the binding production line is as follows:

[0058] First, the staff respectively places the desk calendar frame and the inner page of the desk calendar on the desk calendar frame feeding station 90 and the inner page feeding station 100. The book pushing blocks and the book blocking blocks on the chain book pushing mechanism 150 are extended to the front side of each mechanism, which is used to convey the desk calendar frame and the inner page to the station where the straightening mechanism 110 and the punching mechanism 120 are located. The straightening mechanism 110 straightens the desk calendar frame and the inner page. The punching mechanism 120 punches the edge position of the desk calendar frame and the inner page, so as to facilitate the subsequent ring feeding.

[0059] The punched desk calendar frame and inner pages are transported by the stacked book clamping mechanism 130 to the work station of the automatic ring threading device. The work station is symmetrically provided with two groups of automatic ring threading devices, which respectively thread the two side edges of the desk calendar frame and the inner pages, thereby connecting the desk calendar frame and the inner pages.

[0060] After the ring threading is completed, the desk calendar is transported by the stacked book clamping mechanism 130 to the upper side of the arc-shaped material guide plate 160, and is slid along the arc-shaped material guide plate 160 to the book collecting mechanism 140, and is finally transported out by the book collecting mechanism 140.

[0061] In addition, the front end of the desk calendar frame feeding work station 90 is also provided with a writing pad or book feeding work station 170. This device can be used for binding writing pads or books in addition to binding desk calendars. When binding writing pads or books, the staff places the writing pad or book into the writing pad or book feeding work station 170, and the chain book pushing mechanism 150 directly pushes the writing pad to the book aligning mechanism 110 and the punching mechanism 120, without using the desk calendar frame feeding work station 90 and the inner page feeding work station 100. The subsequent work flow is similar to the above flow, and will not be described here.

[0062] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of ordinary technical personnel; when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist and is not within the protection scope required by the present application.
